The P380 mags have a shallow dimple and the retention plate is easily displaced. I've dropped my holstered P380 and it struck mag base down and the base plate flew off, and those parts plus the cartridges and the spring flew everywhere. They aren't made to withstand repeated drops and especially not onto concrete or other hard surfaces. Any mag needs some kind of bumper or pad added for that kind of abuse.
